A pdf of a book produced by the Bank of Finland is available from its website.

The book covers the story of the Euro banknotes from the start of the project up to the introduction of the second series.
There are lots of illustrations. Well worth a read for anyone who is interested in the story of the Euro.
Available in Finnish and in English.

This is an excellent overview of the euro banknote project and the huge commitment required to bring it to fruition. However, it appears that after a good start, the currency has not really connected with the general public. The introduction of the Europa Series and the trend to a more generic design has further worsened matters. Finland no longer prints its own euro notes and now with the absence of national identifier, there are no longer euro banknotes identifiable as Finnish. Unfortunately, it seems that Ireland is set to follow a similar course.
